ObjectiveTo compare the effect of three different wetting liquid supply modes for noninvasive ventilation. MethodsNinety patients who accepted noninvasive ventilation between February and October 2014 were randomly divided into three groups with 30 in each. Patients in group A underwent humidification with traditional kettle water; those in group B received humidification by one-time automatic water supplying; and patients in group C received continuous infusion to add water for humidification. The wetting effect and humidification related situations among the three groups of patients were compared and analyzed. ResultsThere were statistically significant differences among the three groups in terms of wetting effect, comfort degree, water renewal cycle, working time and economic cost (P<0.05). Good wetting rate of group C was superior to group A and B (P<0.05), but there was no statistically significant difference between group A and B (P>0.05). Humidification comfort degree of group C was obviously higher than that in group A and B (P<0.05), while there was no statistically significant difference between group A and B (P>0.05). Water renewal cycle and working time of group C were significantly shorter than those in group A and B (P<0.05). At the same time, economic cost of group A and C was significantly less than that of group B (P<0.05), while there was no statistically significant difference between group A and C (P>0.05). ConclusionThe kind of continuous infusion for humidification in noninvasive ventilation has a good therapeutic effect for patients receiving airway wetting therapy, which is worthy of clinical popularization and application.
ObjectiveTo understand the relationship between post-traumatic stress disorder (PSTD) and perceived stress in suspected coronavirus disease 2019 (COVID-19) patients quarantined in hospital.MethodsA cross-sectional study of 93 suspected COVID-19 patients in one of grade-A tertiary hospital in Southwest China was carried out to evaluate the incidence of perceived stress and post-traumatic stress symptoms among these patients using the standardized Perceived Stress Scale-10 (PSS-10) and PTSD Checklist-5 (PCL-5), respectively. Pearson correlation was used to analyze the correlation between PCL-5 and PSS-10 scores.ResultsTotal PSS-10 and PCL-5 scores were 16.7±5.2 and 17.0±11.6 in 93 suspected COVID-19 patients, respectively. Positive correlations between PSS-10 and PCL-5 scores were detected (Pearson’s r=0.722, P=0.000).ConclusionsThe occurrence and development of PSTD of suspected COVID-19 patients have the relationship with the early perceived pressure. It suggests that medical staff should identify and intervene the perceived pressure level of patients who are under quarantine as suspected COVID-19 early and effectively, so as to reduce the occurrence of PTSD.
